SPF 27Broad spectrumMineral filters

This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

What the product description says

“Our luxurious sun butter helps skin retain moisture and gives your skin a glowing healthy appearance while providing safe, chemical-free, natural UV protection.”

Source: N/A

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: saccharide isomerate, sucrose.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: beeswax, caprylic/capric triglyceride.

Oryza sativa bran oilKey active· EmollientEffect: HighHelps soften the upper layer of the skin and might have some anti-oxidant properties~0.45–0.65%

Saccharide isomerateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.5–0.75%

Sesamum indicum seed oilKey active· EmollientEffect: HighA good moisturizing plant oil. Due to the high linoleic acid content, it helps soften the upper layer of the skin, reduce water loss and support skin barrier function~0.7–1.05%

SucroseKey active· HumectantEffect: HighCan help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion~0.45–0.7%

BeeswaxKey active· Emollient, OcclusiveEffect: HighForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~0.55–0.85%

SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~0.6–0.9%

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~1.7–2.1%

Cera albaKey active· Emollient, OcclusiveEffect: HighForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~0.65–1%

Cocos nucifera oilKey active· Emollient, OcclusiveEffect: HighAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~1.2–1.5%

Mauritia flexuosa fruit oilKey activeEffect: HighHelps soften the upper layer of the skin~0.35–0.6%

Persea gratissima oilKey active· EmollientEffect: HighAn emollient that helps soften the skin and could be helpful in repairing its barrier function~1–1.2%

Mangifera indica seed butterKey activeEffect: HighHelps to soften the upper layer of the skin and might have some anti-oxidant effect~0.7–1.05%

Hydrogenated vegetable oilKey active· EmollientEffect: MediumAn oil from a mixture of different vegetables. Helps soften the upper layer of the skin~3.8–4.7%

Olea europaea fruit oilKey active· EmollientEffect: MediumAn emollient that helps soften the skin but is not effective for restoring its barrier function. Might be helpful to calm down inflammation~2.9–3.6%

Viola tricolor extract· EmollientEffect: LowA plant extract that might have an anti-inflammatory effect in skin~0.55–0.85%

Aloe barbadensis leaf extract· Humectant, EmollientEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~1.1–1.3%

Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.55–0.8%

Simmondsia chinensis seed oilUnder-dosedEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~0.75–1.15%

Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.5–0.75%

Anti-aging

Not advertised by the brand · 5 ingredients credited for this claim

Moderate support

This product contains centella asiatica leaf extract. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works. The biggest anti-aging effect in this product comes from sun protection. Sun damage is the main factor causing early signs of skin aging. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).

Centella asiatica leaf extractKey activeEffect: MediumA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. It can be irritating to sensitive skin. Might be helpful in preventing stretch marks. It could, however, itself be irritating.~0.5–0.75%

Product summary

"ISUN - Antioxidant Sun Butter SPF 27" "is a broad spectrum sunscreen meaning that it protects both from UVB rays (" burning "- they cause sunburn) and UVA rays (" aging "- they don't cause sunburn but lead to premature aging and pigmentation issues). However, this moisturizer does not offer enough sun protection. We recommend to use a sunscreen with at least SPF 30 daily.

It also works as a moisturizer, so you do not have to use an additional hydrating product.

Sunscreen filters

This moisturizer is a mineral sunscreen. It uses zinc oxide for sun protection. Zinc oxide almost never irritates the skin or stings eyes, but it can leave a white cast.

Irritation risk

There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
